Research Biography Summary

Personal Statement

I trained as a cardiothoracic surgeon in China and participated in several research projects while working as a fellow in cardiothoracic surgery. I moved to the United States for graduate training and received a PhD in physiology from Indiana University in 2005. I began postdoctoral training in Dr. Susan Gunst’s laboratory in 2005. My research has focused on the mechanisms by which cytoskeletal proteins regulate airway smooth muscle contractility. My studies have described several novel mechanisms by which cytoskeletal proteins may regulate contraction and tension development of airway smooth muscle. Recently, I have extended my interests into the pathophysiology of airway responsiveness and inflammation to evaluate signaling mechanisms that may be involved in regulating inflammatory responses of the airways, and to in vivo studies using a mouse asthma model. 

Contribution to Science
My publications directly addressed a novel and detailed hypothesis for a molecular mechanism by which external stimuli regulate Integrin adhesion junction protein complex assembly, organization and activation in airway smooth muscle, which are fundamental components of the signal transduction process and provide a mechanism for airway smooth muscle  to integrate its physiologic responses to humoral and mechanical stimuli. I served as the primary investigator or co-investigator in all of these studies.

  • In addition to the contributions described above, I also published several publications to address of the effects of actin polymerization and its regulation by cytoskeleton proteins on pulmonary inflammation, and may provide molecular target for mitigating the airway inflammation, hyper-reactivity and remodeling associated with allergic airway diseases.  I served as the primary investigator or co-investigator in all of these studies.
